sine qua non. Latin for something essential for another thing to work.

Digital consultancy in Terrassa. We connect the tools you already use, automate repetitive work and build the software you are missing.

Sinequanum, digital consultancy

Your ERP, CRM, website and spreadsheets already hold the data. They need to talk to each other, stop relying on manual copying and reach someone in time.

We are a team in Terrassa. Our company, Sinequanum OÜ, is registered in Estonia. We work with small and medium-sized businesses that have tried three tools and still have Excel open.

What we do

Four areas that overlap in practice. Almost no project fits into just one.

Tell us about your project

  • Automation and applied AI

    Agents and workflows for repetitive work: reading emails and invoices, sorting, replying and moving data between systems. AI where it helps; straightforward rules where they are enough.

    For example:

    • Supplier invoices entered into your accounts automatically.
    • An assistant that answers questions using your company documentation.
    • Alerts when something falls outside the norm.

  • Integrations

    We connect Holded, HubSpot and the rest of your software through APIs, so each piece of data is entered once. If there is no connector, we build one.

    For example:

    • A deal won in HubSpot that creates a quote in Holded.
    • An online store synced with inventory and invoicing.
    • Custom connectors for any documented API.

  • Data and BI

    We bring together information scattered across five systems and turn it into dashboards that update automatically and make sense without asking for a report.

    For example:

    • Sales, margins and payments on one screen.
    • A cash-flow forecast based on your invoices.
    • Clean, organised data before asking AI to do anything with it.

  • Custom websites and apps

    When the tool you need does not exist, we build it: websites, internal dashboards and apps with considered design and maintainable code.

    For example:

    • Company websites with content you can edit.
    • Customer portals and internal dashboards.
    • Apps for field work or the warehouse.

Premium websites for local businesses

Our first in-house product line · In development

A barber, garage or clinic deserves a website with the same care as a big brand: thoughtful photography, clear opening hours and bookings, and a fast mobile experience. We are preparing a format made for local businesses.

How we work

  1. We look at how you work.

    One or two conversations to find where time is lost and which data you already have.

  2. We propose the smallest thing that works.

    A written plan with scope, timeline and budget before we start.

  3. We build it with you.

    Short releases you can try with real data, not a demo.

  4. We leave it working.

    Documentation, team training and maintenance if you want it. If something breaks, you can reach us directly.
